Impact Moling Specialists in England

Impact MolingEnglish Water provides professional impact moling services throughout England, offering a precise and low-disruption solution for the installation of underground water supply pipes. This advanced trenchless technique enables efficient working while protecting existing landscaping and hard surfaces, making it an effective option for both new water supply pipe installations and replacements.

What Is Impact Moling?

Impact moling is a modern trenchless method used to install water supply pipes beneath the ground without the need for continuous open trenches. By forming a narrow underground bore, new pipes can be installed with minimal surface disturbance, reducing disruption and shortening project timescales.

How Impact Moling Works

A pneumatically powered tool, commonly referred to as a soil displacement hammer or "mole," is driven through the ground to create a controlled underground tunnel. Small launch and reception pits are excavated at either end of the proposed route. The mole travels between these points, forming a clear bore through which the new water supply pipe is installed. This approach significantly limits excavation and keeps surface areas largely unaffected.

Why Choose Impact Moling Instead of Traditional Trenching?

Minimal Surface Disruption

Trenchless moling avoids extensive excavation, helping to protect gardens, driveways, pavements, and other finished surfaces.

Fast and Efficient Installation

Impact moling allows water supply pipe works to be completed more quickly than conventional open-cut methods.

Cost-Effective Solution

Reduced excavation and reinstatement requirements help lower overall project costs.

Environmentally Considerate

Moling generates less waste and requires fewer resources, making it a more environmentally responsible installation method.

Key Benefits of Impact Moling

Preserves Existing Landscaping

Gardens, paths, and paved areas remain largely untouched.

Reduces Downtime

Shorter installation periods mean less disruption to properties and operations.

Versatile Application

Suitable for a wide range of ground conditions and property layouts.

Accurate and Safe

Modern moling equipment allows precise installation while protecting nearby underground services.

Our Impact Moling Process

1. Assessment and Planning

We assess the site conditions and identify existing underground utilities to ensure a safe and accurate installation.

2. Launch and Retrieval Pits

Small access pits are excavated at the entry and exit points for the moling equipment.

3. Moling and Pipe Installation

The mole creates the underground bore, and the new water supply pipe is installed through the tunnel.

4. Connection and Certification

The new pipe is connected to the existing system, and certification is issued to confirm compliance with UK Water Regulations.

Frequently asked questions

How does impact moling actually work?

A pneumatically driven tool — the mole — is launched through the ground between two small pits, one at each end of the route. It displaces the soil to form a straight underground bore, and the new water supply pipe is installed through that bore.

How much digging is involved?

Just the two small launch and reception pits. There is no continuous trench, which is what protects gardens, driveways, pavements and other finished surfaces from excavation.

Can moling replace an existing pipe as well as install a new one?

Yes. The technique suits both new water supply pipe installations and replacements of existing pipes, using the same low-disruption bore.
