BELOW-GRADE WATERPROOFING

ABB has more than 20 years experience in the assessment, design and construction management for waterproofing systems; specifically below-grade waterproofing.

Our staff of Professional Engineers, Architects, Building Technologists and Registered Waterproofing Consultants have developed effective waterproofing solutions for more than 200 structures.

With a unique breath of experience, ABB offers consulting on below grade waterproofing for both deep and shallow foundations both in and above local water tables.

Our foundation waterproofing experience includes new and remedial design and consulting for both property line and mass excavation types of foundations. We are familiar with the appropriate use and application of all major types of below grade waterproofing systems including: spray applied, peel and stick sheet applied, sheet membrane, bentonite and composite membranes.

We have unique experience in remedial waterproofing assessment, design and construction administration. Our staff is well experienced in the use of remedial plastic foam grouts, bentonite grouts and surface applied remedial waterproofing materials.

TUNNEL WATERPROOFING

Tunnels vary in size from water pipelines to large-bore tunnels used for transportation. Waterproofing methodology varies depending on the type of soil/ground that the tunnel is built through, the construction method used to build the tunnel and the required dryness level required inside the tunnel.

Cracks can develop in underground structures due to earth load strains, tectonic and seismic influences. Without proper waterproofing the cracks can allow water to migrate into the structure and possibly damage interior finishes or the structure itself.

ABB has experience with both closed systems where the entire structure is 'wrapped' with a waterproofing system and open systems where the waterproofing membrane channels the water to a sidewall drain. ABB can assist you with system selection, waterproofing design and quality assurance monitoring during construction.
