Question
What is a Grade 2 basement environment?
Expert Answer
A Grade 2 basement (BS 8102) requires 'no water penetration,' but some dampness is tolerable depending on the use (e.g., plant rooms, workshops, retail storage). While not as strictly dry as Grade 3 (habitable), it requires robust waterproofing to prevent standing water. We often use Type C systems for Grade 2 to manage any ingress without the need for expensive climate control.
