Technical Foundations for Whitchurch Construction.
In a town with as much development as Whitchurch, from modern urban expansions to sensitive suburban renovations, a Pre-Build Survey is the most critical step in your project’s lifecycle. Building over or near a sewer without professional documentation is a legal and structural risk. Our surveys provide the precise underground intelligence required to protect Whitchurch’s infrastructure and your investment. We identify the exact location, depth, and condition of pipes, ensuring your foundations are designed correctly and your Whitchurch planning application proceeds without a hitch.

Frequently Asked Questions
Why do I need a Pre-Build Survey for my Whitchurch extension?
A Build-Over Agreement is required if you are building within 3m of a public sewer in Whitchurch. It protects you and the water authority.
Will this survey satisfy Thames Water in Whitchurch?
Yes. We use WinCan reporting software, which is the industry standard accepted by Thames Water and Whitchurch building control.
What happens if you find damage during the Whitchurch survey?
We will provide a clear HD video of the damage and a fixed-price quote to repair it before your Whitchurch build commences.
Do I need a post-build survey as well in Whitchurch?
Often, yes. Water authorities in Whitchurch may require a “Post-Build” check to ensure your construction hasn’t damaged the sewer.
How long is a Pre-Build Survey valid for in Whitchurch?
Usually, these surveys are valid for 12 months, provided no significant groundworks have occurred on your Whitchurch site since the check.
Can you trace the depth of the pipe for my Whitchurch structural engineer?
Absolutely. Our Sonde and Trace technology provides the exact depth data Whitchurch engineers need for footing designs.
Do you work with Whitchurch-based architects?
Yes, we are the preferred drainage partner for many architectural firms across the Whitchurch area for all pre-construction works.
Is the survey messy or disruptive to my Whitchurch property?
Not at all. It is entirely non-invasive. We access the pipes through existing manholes on your Whitchurch site.
