Environmental Benefits Of Masterscreed

Material Usage: Traditional methods of patching and thin bond repairs require cutting out the existing surface, squaring off and re-laying hot asphalt. Masterscreed does not require the repair area to be cut out and squared off. It is applied to the existing hole. In fact, the rough texture of a pothole’s surround aids the adhesion of the material. Masterscreed thereby eliminates the need for disposal of road hardcore.


Noise: With less plant and equipment than a traditional hot patch crew, noise is considerably reduced. The Masterscreed process has no need for rollers, saw cutters, road breakers or asphalt tippers.


Non-Hazardous Materials: All materials are compliant with REACH regulations.


Disruption: A Masterscreed crew can achieve outputs of up to 400 sq.m of patching in a shift. This means sites can be treated and opened to traffic very quickly compared to traditional systems, thereby minimising disruption.

Masterscreed Installation

1. Cleaned: The defective area is cleaned, dried and swept.

2. Screeded: The Masterscreed material is hot-applied to the surface and hand-screeded over the defect, filling any voids and leaving a skid resistant finish.

3. Opened: The material is allowed to cool before opening to traffic.

A13 Jct with A1089 Essex

Client: Mouchel Parkman / Carillion - Area 5 Super Agency.


Site: A13 off-slip onto the A1089, the main route into Tilbury Docks from the M25.


Problem: The carriageway had deteriorated to the point that it needed pothole repairs and was deformed and cracked.


Solution: A temporary solution was sought to restore a safe running surface, arrest further deterioration and recover some of the carriageway profile. This would enable the client time to carry out a detailed site investigation and arrange full carriageway reconstruction. Masterscreed was chosen to provide this short to medium term solution.

Local Authority pre-surface dressing

In this example, a County Council are using Masterscreed to provide additional resource to their own busy patching gangs.

Following the severe winters which have caused much publicised extensive damage to the running surface of many roads, this local authority found a need to bolster their existing crews with additional resources to tackle the increasing number of potholes and patches requiring treatment.

Masterscreed was chosen as it quickly and safely restores the running surface, arrests further deterioration and recovers the carriageway profile.

Road Humps

Road humps are a notorious maintenance issue but Masterscreed repairs and renovates quickly with minimal disruption.

Specialist pre-patching materials regulate and repair the road hump before a coating of Masterscreed is applied over the surface. The surface can be re-marked in the same shift and opened to traffic very quickly afterwards. The picture above is a road hump in East Sussex where 4 similar humps were repaired and re-marked in one night's work.

were patched and repaired with the
hot applied Masterscreed material,
before treating the whole surface with
a screed of the same material.

5 road humps in Lewes town were treated in a single overnight road closure and were completed in less than 4 hours.
