Hard Foam Void Filling for infrastructure & commercial properties.
DWG Infraco specialises in void filling using Bacel® Hardfoam, a lightweight engineering grout designed for both above and below ground applications.
Pre-expanded before placement, it can fill large voids quickly, with application times tailored to the project’s needs.
Bacel® displaces residual liquids and neutralises hydrocarbons, making it ideal for petrochemical installations.
With the ability to fill voids of up to 100m³ per hour using dual pumps, it offers a highly efficient solution.
Our environmentally friendly products have been shown to enhance surrounding plant health. DWG ensures quick, non-disruptive and cost-effective solutions for all project sizes.

Key Hard Foam Void Filling benefits.
Enhances Ground Performance and Long-Term Value
More than just a filler, our foam improves ground strength and stability, supports soil improvement, and protects assets against movement or failure. It’s a proven long-term solution for void remediation and ground improvement, even in the most challenging settings.
Versatile in Extreme or Confined Environments
From underwater applications to confined, hazardous or ATEX-rated zones, our fully air-driven system performs safely and reliably. It also provides thermal insulation, resists washout, and is easily removed when required—offering long-term flexibility.
Environmentally Safe and Non-Disruptive
The foam is solvent-free, non-toxic and inert—safe for use on sensitive sites such as SSSIs. It displaces residual liquids and neutralises hydrocarbons, all while being non-flammable, vermin-proof and recyclable, making it a responsible and low-impact solution.
Fast, Large-Scale Installation with Minimal Disruption
With a rapid 50-minute set time and the ability to pump up to 100m³ per hour, this solution drastically reduces site downtime. It’s perfect for time-critical projects, including emergency void fill and track bed stabilisation, with 6–18m lift capability in under 24 hours.
Lightweight, High-Strength Ground Support
Our pre-expanded polyurethane foam delivers exceptional load-bearing capacity without adding structural weight. It’s ideal for stabilising roads, railways and voids around infrastructure, both above and below ground, without putting pressure on surrounding assets.
