BestMem GroundAD 110

• High adhesion to concrete and enhanced waterproofing.

• High elasticity, tensile strength, and puncture resistance.

• Long lifespan with prolonged use in environments frequently exposed to water.

• Non-toxic, does not pollute water sources upon direct contact with the material.

• Quick and non-toxic application for workers, environmentally friendly.

• The bottom and walls of basements in commercial and industrial buildings.

• Structures requiring protection between the basement and the surface.

• Traffic tunnels for high-speed rail or commercial train systems.

SURFACE PREPARATION:

• The substrate must be thoroughly cleaned (free from water, dust, debris, sand, etc.) and any uneven areas or voids must be properly repaired and leveled.

• Horizontal substrates should preferably be concrete or other dense, solid materials (avoid porous or lightweight substrates).

• Structural elements such as concrete piles, formwork, or support panels on vertical surfaces must be securely fixed to ensure adequate load-bearing capacity.

Notes:

• Ambient application temperature must be above 5°C.

• BestMem GroundAD 110 should be installed by qualified and experienced applicators.

• At overlaps, ensure surfaces are clean and use a roller to apply sufficient pressure to achieve proper adhesion.

APPLICATION PROCEDURE:

Application on horizontal surfaces:

• Unroll the membrane with the polyethylene side facing the substrate, and the adhesive protection layer facing upward to bond with the poured concrete.

• For longitudinal overlaps: remove the protective release liner (approx. 80 mm width) from both membrane sheets and bond them together. Use a roller to eliminate air bubbles and voids.

• For transverse overlaps: clean the overlap area and use the supplied adhesive to bond both the underside (160 mm width) and the top side (120 mm width) of the joint.

• Always remove the protective liner before pouring concrete onto the membrane.

Application on vertical surfaces:

• Fix the membrane to the wall using metal battens, with the polyethylene side facing the wall and the adhesive protection layer facing outward (toward the concrete).

• Fasteners should be spaced 30–60 cm apart depending on load requirements; the batten should be positioned at least 10 mm away from the overlap edge.

• The top edge of the membrane must be sealed to the wall using the supplied adhesive.

• Always remove the protective liner before placing concrete against the membrane.

SAFETY

• BestMem GroundAD 110 is non-toxic and non-flammable.

• However, standard construction safety practices must be followed during installation, particularly regarding fire prevention and site safety.
