About Triton SystemsTriton has been manufacturing a range of chemical
dampcourse and other remedial timber and masonry
treatments for nearly four decades. The company also
supplies systems and products to meet the requirements
of all three methods of structural waterproofing as
defined by BS 8102 2009 – and was represented on
the technical committee responsible for drafting this
standard. Triton is the sole UK distributor of Platon cavity
drain membranes manufactured by Isola in Norway and
also supplies a range of Isola membranes for use in
green roof construction.
Triton’s range of remedial dampcoursing products
includes traditional solvent based systems as well as
modern microemulsion and “gel” type water based
products for more effective injection and penetration
into the structure. Triton’s diverse range is able to deal
with all types of construction and building material
and also includes products suited to thicker walls and
structures with voids or cracks.
A network of Triton Approved Contractors
have access to the TUG (Triton Users
Guarantee) scheme which enables them
to offer insurance backed guarantees to
their clients following the completion of
specialist remedial building works.
Training
To support architects, surveyors and contractors,
a full programme of training courses has been
created including Triton’s own courses on damp and
timber treatments and waterproofing using cavity
drain membranes, as well as three RIBA approved
CPD seminars on basement waterproofing and green/
living roofs. More details can be found at

TRI-GEL
n BBA certified rising damp treatment
n Fast, clean application
n Ready to use, water based gel
n No need for electric pump on site
n Cartridge gun or compression pump application
n Guaranteed effective
A cost effective and guaranteed method of treating rising
damp in brick, stone or block walls. Tri-Gel is a water
based and water soluble thixotropic gel which diffuses
naturally into damp substrates and reacts to form a
water repellent silicone resin network. This network is
permeable to water vapour which means the walls can
“breathe” and dry out naturally. Injected using a cartridge
gun or hand operated compression pump,
Tri-Gel eliminates the need for electric pumps on site.
Installation:Tri-Gel is injected into 12mm diameter holes, drilled
horizontally into the chosen mortar bed at 100 –
120mm centres or at the perp joint, mortar bed junction
(brickwork). See below:
Holes should be drilled to within 20 – 40 mm of the far
face of the wall being treated. Treatment can be carried
out from one or both sides of the wall as appropriate and
convenient. Cavity walls would normally be treated from
both sides. The holes should be filled to within
10 – 20 mm of the front face of the wall and capped with
a plug of sand and cement mortar incorporating Trimix 1
or with a DPC wall plug. Spillages should be washed away
with water before they dry.

TRI-CREAM
n Fast, clean installation
n No high pressure injection pump required
n Virtually odourless, low hazard
n Precise dosing
n No pump cleaning required between jobs
A unique silicone emulsion cream for injection into
brickwork etc. for the control of rising dampness.
Tri-Cream can be used in all types of masonry without
the use of high pressure equipment. The cream is
delivered by hand pressure from a simple displacement
pump and injector lance into a series of holes drilled into
the mortar course. Migrating rapidly into the masonry
pores, the injection cream reverts to a liquid phase and
polysiloxanes are formed in situ.
Installation:Tri-Cream is injected into 12mm diameter holes drilled
horizontally in the mortar bed at centres no greater
than 120mm. The depth of hole is dependant upon wall
thickness – refer to product data sheet. Each hole should
be back filled fully with Tri-Cream to within 1cm of the
surface. When treating cavity walls from one side, make
certain that the holes in each leaf are filled.

TRIJECT RAPID
n Rapid injection
n Water based
n Enhanced spread within substrate
n Low odour
n Dilution stability
n Reduced risk of staining
n Non flammable
A unique water based DPC system which uses novel
surfactant technology to match the rapid penetration
levels of solvent based systems. Designed to be injected
into walls affected by rising damp, Triject Rapid forms a
continuous barrier to the passage of rising moisture by
forming a water repellent Silicone resin network within
the capillaries of the substrate. The special formulation
allows for faster injection into most substrates, even
brick, when compared to traditional water based systems.
The Silicone resin network is permeable to water vapour
which means that the walls can “breathe” and dry out
naturally. Supplied in concentrate form.

TRITON INJECTION MORTAR (T. I .M)
n Prevents rising damp in walls
n Especially suitable for thick or random
rubble filled walls
n Odourless
n Gives off no toxic vapours
A one component injection mortar designed to stop rising
damp in brickwork, blockwork, random rubble filled walls
and all types of masonry. T.I.M should be injected into
pre-drilled holes using a hand caulking gun.
Triton Injection Mortar is based on Ordinary Portland
Cement, selected fine quartz aggregates and active
waterproofing chemicals. It activates due to a chemical
reaction between moisture in the structures and
waterproofing chemicals in the mortar which forms a
crystalline growth that blocks the capillaries, pores and
fine cracks in the mortar joints.
Preparation/Installation:Holes should be drilled using 19 – 22 mm drill bits at
overall spacings of 110mm and at an angle of depression
of about 30°, finishing in a mortar bed at the level of the
proposed DPC. In solid walls up to 460mm thick drilling
from one side to the thickness of the wall (and at the 30°
angle) should result in a hole terminating 50mm or so
from the far side. It may occasionally be advantageous
to drill from both sides ie random stonework with rubble
infill or thick walls. Drilling should stop just over half way
through the wall, the holes being at staggered centres of
110mm. Prior to application, all holes should be flushed
out with water to remove any dust. T.I.M should always be
injected into damp holes.
In walls less than 120mm thick, rather than drill holes,
the mortar bed should be raked out at the desired level
to between one third and one half its depth.
Mix T.I.M at the ratio of two to three parts water by five
parts powder by volume. Add the water to the powder.
Mix thoroughly until a smooth cream is achieved, using
a mechanical whisk if possible. Do not mix more mortar
than can be used in 20 minutes.
Using a hand caulking gun, insert the nozzle into the
holes to the full depth and backfill slowly, stopping
approximately 50mm from the top of each hole. Top up
to this level if necessary. Holes should then be plugged
with 3:1 washed sharp sand:cement using Trimix 1
Render Additive.
Replastering:Replastering using a salt retardant render additive such
as Trimix 1 is essential if hygroscopic salts and residual
moisture are to be successfully held back.
Specification:In accordance with NBS Specifications ‘C45 Damp Proof
Course Renewal/Insertion 30 Chemical Injection DPC
System’ and ‘C45 Damp Proof Course Renewal/
Inspection 220 Chemical Injection DPC System’.

TRIMOTIC
ELECTRO-OSMOTIC DAMP PROOFING SYSTEM
n Chemical free
n Suitable for virtually any type of wall
n Eligible for insurance backed guarantees
n Minimal running costs
Trimotic is a chemical-free damp proofing system that
utilises the principle of Electro-Osmosis. Electro-Osmosis
occurs when an electrical potential is applied across a
damp porous material which causes a force to be exerted
on the water which then moves towards the cathode (earth).
The Trimotic system involves inserting platinum coated
titanium wire anodes into the wall at regular intervals.
These anodes (which are joined together by plain
titanium wire) are placed around the building in a ring
main-like configuration. One end is connected to a low
voltage power supply and the circuit is completed at
the other end by an earthing rod (cathode) driven into
the ground to a level below that of the anodes and
at a distance of at least two metres away from the
nearest anode. The completed and operational system
then provides the electric potential, which stops the
rising damp and allows the wall to dry out. Removal
and replacement of salt contaminated or damaged
internal plastering is carried out as usual and to the
normal specifications used when replastering after the
insertion of a chemical damp proof course.
THE THREE KEY COMPONENTS OF THE TRIMOTIC ELECTRO-OSMOTIC SYSTEM
Power unitThe simple and robust power unit
plugs into a 13 amp socket. The plug
connected to the unit’s output lead
simply fits into a socket fitted to the
titanium wire of the installed system.
Power delivery from the unit adjusts
automatically to the degree of
dampness in the wall thus ensuring
the best possible results.
AnodesThe anodes are supplied spliced
into pure titanium wire. Each anode
consists of a titanium wire substrate
coated with platinum. The platinum
is very resistant to oxidisation and is
used to ensure excellent long term
electrical conductivity into the wall.
Earthing RodsThe earthing rods complete the
circuit. The electrical potential
created by the power unit is between
the anodes and earthing rod(s),
therefore it is important to achieve a
good earth contact.

PRINCIPLES OF INSTALLATION
1) Before a Trimotic Electro-Osmotic system can
be considered a full survey of the property should
be carried out. Floor levels inside and out, wall
construction type(s), floor construction etc., should
be determined alongside the diagnosis of dampness
itself. Once rising damp has been correctly diagnosed
attention can be turned to the practical considerations
of where power units and earth rods can be positioned
and what the best route for the installation of the
anodes might be.
2) Installation of the anodes can be from the outside
or the inside of the building, in either case the internal
rendering will almost certainly need to be removed due
to salt contamination. If not, at the very least skirting
boards will need to be removed to allow access to the
base of the wall when internal installation is carried out.
3) The anodes are inserted into the wall via holes
drilled from a mortar bed down at an angle (varying
from 10° to 30°) The titanium wire between the anodes
is placed into a 20mm chase or groove cut into the
mortar bed.
THE PROCESS TYPICALLY PROCEEDS AS FOLLOWS:
c) Form the first anode into a 'J' shape ensuring that all the platinized wire will be inside the wall.
a) Cut a groove 20mm deep into mortar bed.
b) Drill into wall from mortar bed to at least 1/3 thickness of wall.
f) Wet the anode holes with a watering can and then fill with a cement and water slurry.
d) Run the wire along the wall and push the anode into the back of the hole.
e) Pull the wire taught, mark and drill the wall, form the second anode and fit into the hole.
i) Spurs can be created for return walls etc. by joining anode wire using the crimps. A continuous loop of wire is not required.
g) Point up the groove containing the titanium wire.
h) Doorways and other openings are bridged using plain titanium wire attached to the anode containing wire using the titanium crimps.
The titanium wire should be considered to be live (although at a very low, safe voltage as far as people and animals are concerned) and should not come into contact with any other metal such as central heating pipes, electrical boxes or wiring etc.
Insulating sleeving or tape should be used to isolate vulnerable wire.
Warning labels are supplied for attachment to the wire for display in prominent places.
j) Place an earth rod into the ground at a lower level than the lowest anode.
k) Connect the earth rod and power unit(s) (one power unit is sufficient for 100 anodes) and switch on.

TRITON RENOVATING PLASTER
n For plastering most traditional background materials during renovations
n �Particularly suitable following the installation of a new damp proof course
Triton Renovating Plaster is a lightweight, cementitious
plaster which has been developed to control dampness
passing through plastered walls of old properties. Triton
Renovating Plaster is designed to have similar properties
to a 1:1:6 cement:lime:sand plastering mortar but with
Perlite lightweight aggregate replacing the sand. Man-
made fibres are incorporated into the mix to control
shrinkage and improve flexural strength.
Installation:Once the old plaster has been removed and the DPC
installed, Triton Renovating Plaster is applied before the
finishing coat to hold back residual moisture and salts.
To be used in accordance with recommendations in
BS 5492. Triton Renovating Plaster is compatible with
most building materials. The waterproofing additive and
Lime content minimises efflorescence and rusting of
metal lathing and conduits, at the same time controlling
pattern staining and mould growth.

TRIMIX 1
n BBA certified product
n Improves workability of mix
n Delivers water and salt resistance to mix
n Suitable for internal and external use
A water and salt resistant additive for cement mortars
which is designed to improve the workability of the mix
and, after curing, imparts water repellency and salt
resistance. Trimix 1 also reduces the amount of water
required to provide a workable mix and hence produces
a more dense render. Trimix 1 is suitable for use with
mortars and renders for internal and external use but
is particularly recommended for use in internal cement
rendering (replastering) of walls which have received a
damp proof course.
Installation:One litre of Trimix 1 should be diluted with 25 litres
of water. The diluted Trimix should then be used as
gauging water without further dilution. In replastering
internal walls affected by rising damp, the recommended
specification is that Trimix 1 should be added to the
first (10mm) coat of cement mortar only. This should be
followed by a second coat without the addition of Trimix
1 which should be applied after the first coat has set but
before it has dried. The finishing coat should be a porous
lightweight plaster skim applied after the cement render
coats are fully cured.

TRI-REND
n Improves workability of mix
n Suitable for internal and external use
n Delivers water and salt resistance to mix
A waterproofing, salt inhibiting and plasticizing additive
for sand and cement renders and mortars. Tri-Rend
improves workability to the mix and, after curing,
imparts water repellency and salt resistance. Tri-Rend
is recommended for use in mortars used for internal
cement rendering (replastering) of walls affected by
rising dampness.
Tri-Rend is an alkali metal soap of aliphatic fatty acids
dissolved in water. The concentrate is alkaline
(about pH11).
Installation:One litre of Tri-Rend should be diluted with water to make
40 litres. The diluted Tri-Rend should then be used as
gauging water without further dilution. In replastering
internal walls affected by rising damp, the recommended
specification is for Tri-Rend to be added to the first
(10mm) coat of cement mortar only. This should be
followed by a second coat without the addition of
Tri-Rend which should be applied after the first coat has
set but before it has dried. The finishing coat should be a
porous lightweight plaster skim applied after the cement
render coats are fully cured.
