Type A waterproofing comprises various categories of ‘barrier’ system, designed to be applied to the concrete or masonry structure. This section covers Fully Bonded Sheet Systems, but other Type A Systems available from Triton include Liquid Applied and Cementitious.
Our Type A systems include:
These fully bonded membranes are typically used in basement waterproofing as well as to waterproof foundations, roofs, lift shafts and lift pits, balconies and other below ground structures such as car parks.
A premium, pre-applied concrete waterproofing system incorporating a mesh membrane and stretchable sealing tape.
The fully-bonded, pre-applied (applied prior to pouring concrete) system comprises the unique Triton Shield Membrane and Triton Shield Stretch Tape that, when used in combination, offer a cost effective, fast to install, very lightweight and durable solution for waterproofing protection.
A self-adhesive membrane designed for gas-proofing and waterproofing/tanking of underground structures where harmful ground gases are anticipated.
Triton Hydrolock, when used with properly designed concrete, can be used as fully bonded Type A waterproofing protection as defined in BS 8102: 2022 for the waterproofing of new structures.
Triton Hydrolock is a bentonite membrane (often known as a ‘bentonite carpet’) comprising a mechanically bonded Geosynthetic Clay Liner (GCL) composite of pulverised bentonite, embedded between two layers of geotextile. The internal natural sodium bentonite swells in contact with water to form a low permeability waterproofing barrier.
BBA certified Triton Hydrolock can be used externally on concrete to provide an effective barrier to the transmission of liquid water where Grades 1 to 3 waterproofing protection are required as defined in table 2 of BS 8102: 2022.
A unique, stretchable, waterproof and gas proof sealing tape. Triton Shield Stretch Tape speeds up membrane installation by conforming to the shape of curved, convex or concave profiles. Suitable for use in the installation of damp proofing, waterproofing and gas proofing membranes, this highly versatile tape can be used at the wall/floor junction; to seal abutting or overlapping membrane edges, or wherever a seal is needed around awkward, contoured or shaped corners. Up to a 90o turn is achievable without the need to cut the self-adhesive tape.
Being water and vapour resistant, TWS-EX100 has many waterproofing applications including foundations, basements, roofs and decks, lift shafts and pits, car parks, subways, bathrooms and balconies. A unique feature is its selvedge that enables a fast and secure seal on all side edge laps.
TWS-EX100GM is a highly efficient waterproofing membrane which also acts as a barrier to Radon, Methane, Carbon Dioxide and other ground gases and contaminants. The self adhesive membrane uses aluminium as the primary barrier, which is reinforced and protected by a laminated film of biaxually oriented HDPE film to one side and a robust bitumen rubber to the other. A selvedge of bitumen rubber facilitates easier lap seals.
Triton supplies a full range of ancillary products for the installation of fully bonded sheet (Type A) waterproofing systems. This range includes primers, reinforcing tapes and a cement based sealing product.
