Dual Seal Bentonite/HDPE Waterproofing Membrane
Description
Dual Seal is a high performance self swelling, self healing waterproofing membrane comprising of a thick, tough, high density polyethylene sheet laminated to 4kg/m2 of quality Bentonite granules. The Bentonite used in the manufacture of Dual Seal is capable of repeated cycles of wetting and drying without deterioration of its sealing properties and has a life expectancy measured in thousands of years (BBA Certified). It has WRAS approval for use with potable water.
Uses
Dual Seal waterproofing membrane has been specifically developed for use as a high performance waterproofing membrane to provide a totally watertight barrier in below ground concrete construction, including basements, underground car parks, plant rooms, access tunnels etc.
Dual Seal Membrane can be installed in damp conditions and is, therefore, particularly suitable for use as a roof waterproofing system for earth covered potable water reservoirs.

Bitusheet XL Self Bonding Waterproofing Membrane
Description
Bitusheet XL waterproofing membrane consists of a self bonding polymer modified bitumen which is covered on one side by a tough multiply cross laminated polythene film and protected on the other side by a release sheet which is removed prior to the bonding of the material on to a suitably prepared substrate. Once the release sheet has been removed the membrane can be easily applied by roller pressure. Available in Temperate and Hot Climate grades, incorporating a 50mm selvedge on one edge to form homogenous overlap joints.
Uses
Bitusheet XL is intended for use as a self bonding vertical or horizontal damp proof membrane in tanking below ground structures, subways and retaining walls.

Bitusheet Heavy Duty Membrane Protection Board
Description
Bitusheet HD Protection Board is a tough, flexible polymeric board specifically developed for protecting the Bitusheet range of self adhesive waterproofing membranes, against mechanical damage, foot and normal site traffic and abrasive backfill materials. Due to its high strength and excellent puncture resistance the Bitusheet HD Protection Board exceeds the performance of thicker protection boards. It can be easily cut and shaped on site.
Uses
Bitusheet HD Protection Board is designed for both horizontal and vertical applications to protect Bitusheet Waterproofing Membranes against abrasive backfill materials, and poured concrete. The board should be butt jointed and supported during backfilling. Bitusheet Double Sided Tape or SCP Joint Filler Adhesive should used to spot bond the protection board to the membrane. The joints should be staggered, and also staggered over the membrane laps. Butt joints should be overtaped to prevent fines being washed through onto the membrane.

Aquatek Super
Description
Aquatek Super is a Cement-based hybrid slurry coating for the waterproofing of concrete which waterproofs by acting as a water-repellent coating and pore blocking through the saturation of the capillaries.
Uses
Aquatek Super is a waterproof and protective coating for concrete. It is suitable for application under positive or negative water pressure, both below and above ground. Basements, underground structures, water reservoirs, water
tanks, water treatment plants, tunnels, swimming pools, canals, conduit pipes, ponds etc. can be permanently sealed with Aquatek Super.

Bitusheet Mastic Filler is a bituminous mastic of trowelling consistency.
Uses
For the filling of cracks in concrete prior to carrying out full waterproofing treatments with materials such as Bitusheet waterproof membrane. Also used for sealing of exposed edges, bolt holes, general gap filling and fixing Bituflex fillet and Bitusheet protection boards. Ensure the surface is clean, free from loose matter and dry. Apply the mastic with a trowel, filling crack completely. Bed the Bituflex fillet into the mastic while still tacky. Allow to dry before applying membrane.
