Introduction

This publication hasbeen prepared asa

guide to brick construction for the home

builders. It is especially for the builder who

may not be famili ar with all areas of brick

construction in the home building field.

We have attempted to cover parti cularly

those details of construction w hich wil l be

most often used. H owever, since we cannot

cover all possibili ties we hope you will ask

for additional information when needed.

Typical Brick Cavi ty Wall Details

Brick Cavity WallA cavity wall consists of two wythesof masonry

separated by a continuous air space that is

between two and four inches in wi dth. T he

cavity wall is utilized because it i s an excep-

tional all-weather wall. B ecause of its ease of

insulation, it i s an efficient energy saver. The

cavity wall helpsresist noise penetration, i s fire

resistant and is virtually mai ntenance free.

The two walls are tied together with metal ties.

Spacing and type of ties can vary and should be

determi ned on a case by case basis.

The bri ck cavity wall, a drainage type wall, is

particularly imp ervious to moisture penetration

because the air cavity ( space) allows any mois-

ture to drain to the bottom of the wall. Proper

flashing and weep holes are important to drain-

age. Flashing di rects moisture from the interior

wythe to the outside of the exterior wythe.

Flashing should be i nstalled over all openings,

under sills and, most importantly, at the bottom

of the cavity wall just above ground level.

For addi tional i nformation you may request

Tech Note 21B, Brick Masonry Cavity Wall s

Detailing.

T ypical Brick Veneer Wall Details

Brick Veneer WallBrick veneer wallsare currently the most widely

used walls for residential construction. T he brick-

work i s a veneer since it is a non-loadbearing

facing built after framing is complete. This is a

drainage type wall. A n air space is provided

back of the brickwo rk to allow any penetrating

water to fall to the base of the veneer where

flashing and weep holes are provided to di vert

water back out of the wall.

Footing size and foundation anchorage should

be determined per local building codes.

Foundations should extend not less than 12

inches below the fini shed natural grade or

engineered fill and i n no case less than thefrost line depth.

Insulating Brick Walls

Insulating The Brick Veneer Wall

T he brick v eneer wall may be insulated by

use of standard insulating sheathing and fiber

glassbatt insulation placed between studs,

giving an R value of approximately 14,

and a U value of approxim ately 0.07.

M ass of the brick veneer and the nominal

one inch air space between veneer and

sheathing adds greatly to energy efficiencyof the brick veneer wall.

Insulating The Brick Cavity Wall

O ne of the most important advantageso f

the brick cavity wall i s that the cavity may be

used for placing insulation withi n the wall.

In order to insulate the wall properly it i s

absolutely essential that the cavity be kept

clean during construction.

Insulations that have been used in cavity

walls include loose fill poured type, rigi d

board type and foamed-in-place type.

R value for a 12 inch brick and brick

cavity wall insulated with p oured vermiculite

or a 2 inch rigid styrene board would be

approxi mately 14, and the U value would

be approximately 0.07.

M ass of the brickwork provides additional

energy saving quali ties not recognized in

standard U value calculations.

Fireplaces

FireplacesToday, bri ck fi replaces are considered standard

in almost all homes. The need for a backup o r

secondary heati ng system has created a renewed

interest in the open fireplace that has historically

been the H eart of the H ome.

Todays fireplace is subjected to higher tempera-

turesand more prolo nged use than at any other

time i n memory. Because of i ncreased tempera-

turesand l ength of use, the hom e builder m ustascertain i f his fireplace design meets all require-

ments of the Buildi ng Code and insure that con-

stant supervision be given to the carpentry and

masonry crews during construction of the struc-

ture and surrounding frami ng. Since the safety

of human life is involved, these details should

not be left solely to subcontracting crews.

Also, special attention should be given to deter-

mining the type of chimney footing required.

Buildi ng Codes require that concrete footings

for chimneysrest on solid ground, and/or

extend down to the level of main foundation

footings and that they be bonded with m ain

footings. Solid G round meansfirm, undisturbed

soil or adequately controlled fi ll.

Mortarless InteriorBrick Flooring

M ortarless brick flo oring may be placed on

a concrete slab or on a wood flooring system

as shown i n the ill ustrations.

The size of the brick i s optio nal, except for

patternssuch asbasket weave and herring-

bone, which require brick wi th length dim en-

sions exactly twice that of the wi dth, such

as 4"x8" or 3 3/4"x7 1/2", etc.

Thi cknessof brick used on a concrete slab

may vary up to 2 1/4", but maxi mum thi ckness

of 1 5/8" is recommended for wood flooring

systemsto reduce weight. Joist spacing of w ood

flooring systems should be li mited to 12" o.c.

Buil ding paper is first placed on the supporti ng

base with edges butted rather than lapped. T wo

layers of 15 lb. felt are recommended. Brick are

placed directly on the felt in the desired pattern.

Uni ts should be placed tightly together.

Clean, dry sand is then placed on the brick

and swept into all j oints. Surplussand is swept

off and sealer may be appli ed when floor is com-

pletely dry. Sealing is necessary asit lo cks sand in

jointsand creates an imperviousfloor finish.

Because sealing is so important, i t is suggested

that great care be given to choosing and applyi ng

a ceiling product. For specific questions on sealing

concerns, contact the technical depar tment at

Brick SouthEast.

Size of the fireplace should be in proportion

to the room size. The U.S. D epartment of Agri -

culture has determined that a fireplace 30 to 36

inch wide i s generally suitable for a room hav-

ing 300 square feet of floor space.

A fresh air suppl y substantially increasesthe

effici ency of a fireplace by reducing the amount

of heated air tak en from the livi ng space. D etails

of the adjustable fresh air damper and ductwork

are shown.

The fi replace builder should be cautioned to

leave room in m asonry work fo r expansion of

metal lintels, dampersand firebrick li ningsi n

order to avoid masonry cracks.

Arches

6

ArchesThe arch provides a method of spanning mason-

ry wall openings that not only has structural

advantages over lintels and beams, but gives

designers a method of expressing various archi-

tectural effects and styles.

Arches are constructed wi th the aid of tempo-

rary forming o r centering w hich must carry

dead loads until the arch hasgai ned sufficient

strength to suppo rt itself and other superi m-

posed loads. G enerally, forms should remain

in p lace a mini mum of ten daysafter completion

of all masonry work to b e suppo rted by the

arch. To help simpli fy construction of flat or jack

arches, a steel angle ( lintel) is sometimesused asa

permanent form in bri ck veneer construction.

Complete filling of all mortar joints is especially

imp ortant in arch construction since joi nts are

vital in maintaining the compression ring or

wedging effect of the arch. Any movement

caused by the slightest sliding, settlement or

rotation of abutments or supportsor the arch

itself may result in failure of the arch.

O rdersfor bri ck archesshould be placed with

the brick manufacturer at the inception of the

job, and detailed drawings, preferable full draw-

ings of a half arch, should accompany the

order. The following i nformation should be

on drawings:

1. M asonry Opening D imensions

Exterior Paving

Exterior PavingBrick walk ways, patios and driveways are more

popular now than ever before. Hom ebuilders

are finding brick paving a must in todays

highly competitive market. Brick paving is an

easy way of adding value to the property you

are putting on the market.

M ortarless paving is much cheaper to build than

mortared paving and, if built properly, can pro-

vide the same enduring qualities of conventional

pavi ng systems and materials.

T he most impo rtant consideration for mortar-

less paving i s a good base. Soli dly compacted

earth and other base materials wil l generally elim-

inate settlement problems. Go od drainage of

the general area where mortarlessp aving is to

be installed wi ll help mai ntain a stable base and

help prevent growth of algae on paving units.

Providing good edge retention of mortarless

paving is essential, and, of course, specifying

weather-resistant brick paving units is important

to a quality installation.

steps are normally expo sed to severe weathering,

quality materials and good work manship are essen-

tial for good construction and performance.

Al l brick steps should be placed on concrete

footi ngs. Concrete should be 2500 PSI ( 28 days)

placed in an area excavated to solid earth with

a 12" minimum depth below finished grade. All

footings should be a minim um of 8" deep and

have a 4" projection past steps except where they

abut an adjoi ning wall. In situations of question-

able soil conditi ons, reinforcing steel should be

used. A ll masonry used in steps should be lai d

with type S mortar.

Rowlock tread steps having 7" risers and 12"

treadsshould b e buil t using factory-made corners

which are available from all bri ck manufacturers.

For specific tread and riser dimensions, consult

with your local code official.

Driveways

DrivewaysSpecificationsM ortarless brick pavi ng should conform to the

alignment and grade as shown on the plans.

T he subgrade (earth) should be well compacted

with all organic material and soft soil removed

and replaced with an approved soil. Paving

brick should conform to ASTM C902, C lass

SX. C olor and dimensions should be approved

from a sample. M ortarless brick pavi ng may

be i nstalled by semi-ski lled labor.

Installation1. Install a row of curb brick on one side of

the driv eway, settling units to the required

height. Use mortar behind and under curb

units as needed for support. Set a temporary

form on the opposite side of driveway to

proper grade, 2-3 inches outside of the

location of curb brick i nstallation.

2.A base course should be p laced and com-

pacted. The base material should be of

Aggregate Base Course (AB C) conforming

to D O T specifications. T he aggregate

should be placed on an approved subgrade

between the curb brick row and the tempo-

rary form. T he aggregate can be compacted

with a vibratory place compactor or by hand

and should have a slight crown upon comple-

tion. When compaction i s complete the base

course should be smooth, hard, dense, un-

yielding and well bonded.

Perspective

3. Place a 1/2" to 1" layer of sand or stone

screenings on the base course, using screed

to spread uniform ly over the entire area.

M oisten and compact by hand or a mechani-

cal devise. Rescreed this layer as required

to bri ng surface to the exact grade.

4. Begin laying paversalong previously installed

rows of curb brick , using specified bondi ng

pattern and continui ng until all paving is laid.

Norm ally, paving units are placed tightly

together leaving no space between individualpavers. H owever, if units have very smooth

uniform edges or if paversare very uniform

in size, 1/16" should be left between units to

allow a space for sand to surround each unit.

5. Remove the temporary form. Install final row

of curb brick ti ghtly along the outer row of

paversby removing groups of 5 or 6 pavers

from the outer row and excavating a small

trench for the curb brick in thi s area. Place

the curb brick i n this trench, backfi ll and

tamp on both sides and use mortar behind

and under units as needed for support. Set

curb units to required grade. Replace and

smooth screenings and replace paving brick.

6. Scatter stone screenings or sand over entire

surface and sweep i nto cracks.

Walkways & PatiosSpecificationsM ortarless brick p aving should conform to the

grade asshown on pl ans. The subgrade (earth)

should be well compacted with all organic material

and soft soil removed and replaced with an

approved soil. The p aving brick should conform

to ASTM C902, ClassSX. C olor and dimensions

should be approved from sample.

Installation

1.I nstall a row of edge brick on one side of

the walk to the required ali gnment and grade.

Set a temporary form on the other side of the

walk to the proper grade, 2"-3" outside of

edge brick location.

2.C omplete grading asshown in sketch below

the formsto approxim ate required depth using

the screed to spread uni formly ov er the area.

M oisten screenings or sand and compact by

hand or mechanical equipment. Rescreed

screenings or sand, as required, to smooth

base and bring surface to the requi red grade.

3.Start laying pavers along the previously

installed row of edge brick, using specified

bonding pattern, and continue this until all

pavers are laid.

Normally, paving units are placed tightly

together, leaving no space between individual

pavers. H owever, if the units have very

smooth uniform edgesor if pavers are very

uniform i n size, 1/16" should be left between

units to allow a space for sand to surround

each uni t.

4.R emove the temporary form. I nstall final row

of edge brick tightly along outer row of pavers

by removing groups of 5 or 6 pavers from

outer row and excavating a small trench for

edge brick i n this area. Place edge brick in

this trench, backfi ll and tamp on both sides,

repleni sh and smooth the screenings or sand

and replace paving bri ck.

5.Scatter stone screenings or sand over enti re

Brick Cleaning

Four Simple Steps For Better Brick Cleaning

O ften forgotten, brick cleaning is actually one

of the most imp ortant parts of new home con-

struction so far as the Home B uyer is concerned.

Why not gi ve brick cleaning the same concern

given other Final Appearance items?

Brick cleaning is not difficult if properly done.

First thing to do is to ask the brick manufacturer

for recommendation on cleaning the parti cular

brick. If a decision is made to use an acid clean-

ing system, then a parti cular acid product should

be agreed upon.

Before applying acid solution, larger mortar par-

ticles should be removed by use of hand tools,

reducing unwanted mortar deposits to paper-

thin smears.

Nex t, app ly plenty of water to the masonry,

enough to satisfy thirst of the wall and k eep

water standing on surface of masonry.

Brick Does Not Leak

O ccasionally one may encounter the problem

of a l eaky wall. Ex perience shows, however,

the cause of the problem is not the brick, but

improper construction technique.

The following improper conditions may con-

tribute to the leaky wall prob lem and should

be avoided:

Poor bond between brick and mor tar

Use of raked or scratched join ts

Use of poor qua lity mortar

Excessive morta r dr oppings in ai r space or cavity

Poor foundation walls

In spite of the need to supervise all aspectsof

construction, it is obvi ous one cannot be every-

where and do everything. For thi s reason, we offer

this information to acquaint you with some basic

Cold Weather MasonryConstruction & ProtectionRecommendations*

Cold weather masonry construction and its

quality control require some additional attention

to construction practicesand pro tection. Atten-

tion should be directed to the following details

as well as those normally attended.

1. The cold weather construction and protection

recommendation of thi s recommended prac-

tice should be closely followed.

2.C onstruction materialsshould be received,

stored, and protected in ways that prevent

water from entering the materials.

3. If climactic condition warrant, temperatures of

construction materi als should be measured

frozen sand and wet masonry units must be

thawed. M asonry units below 20oF must be

heated above 20oF without overheating.

*Thi s brochure containsgeneral cold weather constructionrecommendations. Code specific recommendations for hot

and cold weather construction can be found i n the M asonry

StandardsJoint Commi ttee document.

Recommendations

4.Sufficient mortar i ngredientsshould be heated

to produce mortar temperatures between 40oF

and 120oF. Every effort should be made to

produce consecutive batcheso f mortar with

the same temperaturesfalling wi thin this range.

The mortar temperature after mix ing and before

use should be above 40oF, maintainable either

by auxili ary heaters under the mortar board

or by more frequent mixing of mortar batches.

H eated mortar on mortar boards should not

become excessively hot ( greater than 120oF).

5 During below-normal temperatures, masonry

should be placed only on sound unfrozen

foundations. M asonry should never be placed

on a snow or i ce-covered surface, because of

the danger of movement when the base thaws

and the possibility of very little bond being

developed between the mortar and the sup-

porting surface.

6.A t the end of the day, the top surface of all

masonry should be protected to prevent mois-

ture, as rain, snow or sleet, from entering the

masonry. T his protection must cover the top

surface and should extend a mi nimum of 2

feet down all sides of the masonry.

Alternate Method forSupport of Brick Veneerabove Garage DoorOpeningsTypi cally garage door openings over 10 feet

are required to be designed by an engineer.

Ho wever, some officials recognize an alternate

method of support that incorporates the concept

of reinforcing the brick veneer. Thi s technique

allows the use of ladder wire joi nt reinforcing inthe first few horizontal mortar joi ntsabove the

openings asdescribed by the diagram below.

We recommend presenting this alternate method

to your local official for approval in advance of

actual construction.

Construction Considerations:

1.T he maximum openings allowed by this

method is 18 feet 3 inches with a mini mum of

1 foot 6 inches of brick required on either

side of the opening.

2.A maximum height of 5 feet of brick may be

supported above the opening provided there is

.

a mini mum of 13 inchesof veneer above the

opening edges (approxim ately 5 brick courses).

3.A maxi mum height of 12 feet of brick may be

supported above the opening provided there

is a mini mum of 2 feet of veneer above the

opening edges (approximately 9 br ick courses).

4.A maxi mum height of 35 feet of brick may be

supported above the opening provided there

is a minim um of 5 feet of veneer above the

opening edges (approxim ately 22 brick courses).

5.Care must be taken wi th the placement of

additional openings (i .e. windows) above the
