Reducing high ground levels in London & Surrey

What Are High Ground Levels?

High ground levels are one of the most common causes of damp in UK homes. Over time, patios, paving, soil, or driveways can be raised above the original damp proof course (DPC), allowing moisture to bypass this protective barrier and enter internal walls.

Why High Ground Levels Cause Damp

Building regulations recommend that the damp proof course sits at least 150mm above external ground level. When this gap is reduced or removed, moisture can travel above the DPC and create damp patches inside your property.

Signs of High Ground Level Damp

• Damp patches at low wall level
• Peeling paint or blown plaster
• Musty odours or mould growth
• Ground level above air bricks

Our Solution: Reduce Ground Levels

At Atruss Preservation, we specialise in identifying and correcting bridged damp proof courses. Our expert solutions include:

• Lowering external ground levels
• Cutting back paving and concrete
• Installing drainage channels or French drains
• Removing render or coatings below DPC level
• Installing new damp proof course systems where required

French Drain Installation

A French drain is a highly effective solution where ground levels cannot be fully reduced. It allows water to drain away from your property while maintaining the correct clearance below the damp proof course.
