Retaining Walls in Wavendon

Wavendon has two quite different kinds of garden. The newer estates around the edge of the village often have rear gardens shaped on filled ground, with banks or developer edging where plots step up or down. The older village has cottages and long-established gardens where a stone or brick wall may have been holding back soil for a very long time.

On newer plots the issue is usually ground that has not finished settling. Soil placed during construction can be softer than it looks, and banks held only by thin timber edging or a turf slope tend to slump after a few wet winters. Before building on that kind of ground, we dig to find firm material for the footing, which on filled plots can mean going deeper than you might expect.

In the older part of the village, the question is often whether an existing wall can be saved. Signs that a wall is struggling include:

• A lean or belly that has grown over recent years.
• Mortar washing out of the joints, especially near the base.
• Water seeping through the face after rain rather than draining behind.
• Stones or bricks pushing forward at the top where roots have got in.

Whichever kind of garden you have, a lasting wall needs the same basics: a concrete footing sized for its height, free draining backfill behind it, and weep holes so water has an easy way out. Without those, even a well built face will eventually be pushed out of line.

Timing matters on newer plots. A garden only a year or two old may still be settling, and building straight onto loose fill can lead to cracks within a few seasons. Where we find soft ground, we either dig through it to firmer material or recommend a stiffer footing, and we explain the difference in cost so you can decide. Old village walls, meanwhile, sometimes carry a hedge or mature shrubs along the top, and we agree with you beforehand whether that planting stays, is cut back by you, or comes out.
