Structural Waterproofing


Protecting structures from water damage

Talk through your latest project with a structural waterproofing expert

The ever increasing demand for more complicated and detailed subterranean structures has led to an increase in demand for unique and bespoke solutions, including combined protection or hybrid systems, designed to stop the ingress of water into these environments.

Grade / Example of use of structure / Performance level

These structures can be defined using Table 2 of the BS8102:2009 as the follows;

Grade 1

Car parking; plant rooms (excluding electrical equipment); workshops

Some seepage and damp areas tolerable, dependent on the intended use.


Grade 2

Plant rooms and workshops requiring a drier environment (than Grade 1); storage areas

No water penetration acceptable, damp areas tolerable; ventilation might be required


Grade 3

Ventilated residential and commercial areas, including offices, restaurants etc.; leisure centres

No water penetration acceptable. Ventilation, dehumidification or air conditioning necessary, appropriate to the intended use.

Many of the problems associated with waterproofing a below ground structure can be alleviated by following a very simple design philosophy outlined in the British Standard.

This design philosophy revolves around the assumption that groundwater will be present at some point during the life of the structure, the assumption that defects will be present in either workmanship or materials and that the consequences of the defects will be unacceptable.

It is with this in mind that Lainton Services Limited supplies, installs and designs structural waterproofing solutions covered by Type A (Barrier Protection) and Type C (Drained Cavity Protection) in BS8102:2009 Table 1.
