Soakaways and Basements, not Always a Good Combination.

Soakaways are a means by which surface water (roof/rainwater) can be discharged into the ground.  These have a range of benefits, in that they deal with surface water where there is no access to mains drains, they place a lesser demand on those systems if they are present, and they can provide a saving on your utility bills versus discharge into a mains system. They are commonly employed within new-build developments and we often see them.

The design of soakaways is a science in itself and should be undertaken by a suitably qualified Civil Engineer. It is not the design of soakaways that I want to comment upon, but their use in association with basement waterproofing systems, and implications upon the waterproofing where soakaways do not function as intended.

Assessing Sites with a View to Assessing Risk.

Part of the process of waterproofing design laid out within BS8102 Code of practice for the protection of below ground structures against water from the ground, relates to assessing the nature of a given site, and then using this information to influence your design.

In essence the ‘nature of the site’, can be interpreted as ‘how wet is it, and how wet is it likely to be’?

This is important because the greatest driver of risk, is essentially how much water there is, or potentially will be in the ground, to pressure upon the basement structure and waterproofing system(s). Continue reading Assessing Sites with a View to Assessing Risk.
