Challenge

The waterproofing of this residential development involved simple external measures and internal drainage solutions.

Solution

The external work involved covering the top of the retaining wall sections with a cementitious slurry tank to limit water permeation into the steel reinforced concrete.

The slab and reinforced concrete wall sections were constructed as standard, with the outer walls built above the proposed ground level. Trace Basement Systems cut chases into the slab (they could have been preformed when forming the slab), and inserted the company's WaterGuard™ sub-floor drainage channels that were connected directly to the drains.

The outer walls and slab were then lined in a cavity drainage membrane, and covered with a screed. The inner block walls were then constructed, featuring sealed plugs to accommodate wall ties.

Outcome

Any groundwater that permeated through the retaining walls was simply drained to the WaterGuard™ sub-floor drainage channels.
