GSE HD geomembrane lined salt ponds ensure long-term brine containment
GSE® HD geomembrane lined over 3.4 million m² of evaporation ponds to prevent brine seepage under extreme heat and UV exposure. This continuous barrier eliminated salt discharge and protected the surrounding environment.
Jefferson Coal Slurry Impoundment Closure
In Jefferson County, Alabama, MIRAFI® CR440 was used with CCR fill to create a reinforced construction platform over soft fine coal refuse, supporting safe equipment access and efficient coal slurry impoundment closure.
Ensuring secure tailings containment at Saudi Arabia’s Umm Wu’al Phosphate Project
Solmax supplied 900,000 m² of double-sided GSE® HD FrictionFlex geomembrane for Maaden’s Umm Wu’al tailings ponds in Saudi Arabia, meeting strict quality controls and ensuring flawless containment in extreme conditions.
The A617 is a primary A-road in Derbyshire and Nottinghamshire (East Midlands) in England. Over time, cracks appeared on the road, and rehabilitation was needed. After careful evaluation, the most cost-effective and technically sound solution was found to be MIRAGRID® PGM G 100/100. This product increases the road's lifetime by serving as an asphalt interlayer system that provides crack retardation, sealing, and stress absorption.
The A617 Millennium Way in Rainworth was opened in 2000. The original construction consisted of a 200 mm (7.9 inches) thick high modulus base, a 60 mm (2.4 inches) binder course, and a 40 mm (1.6 inches) SMA surface course. After a few years of use, signs of reflective cracking from the lower joints became evident throughout the road, and surface course failure (such as alligator cracks and potholes) occurred in large areas. Core samples were taken, revealing good structural integrity in the bituminous layers but no bond between the base and binder course layer. It was assumed that this lack of bond contributed to the surface course failure, as the upper layers flexed over a stiff base. Following consultation with the main contractor Lafarge Tarmac, it was decided to remove the existing material to a depth of 140 mm (5.5 inches) and install a reinforcing asphalt interlayer to ensure a strong bond between the layers and prevent future reflective cracking. Asphalt Grid Systems Limited, recommended by Lafarge Tarmac due to their previous success, was chosen to supply and install MIRAGRID PGM G 100/100.The total area of the project was 12,000 m² (129,166 ft²). Due to the road's layout, which included a dual carriageway, roundabout, and single carriageway, the work was performed during a full road closure, with dual shifts employed to reopen the road as quickly as possible. The asphalt grid and bitumen bond coat were laid over two shifts (Saturday and Sunday evening) to align with Lafarge Tarmac's schedule. The entire project was completed in 9 days, one shift ahead of the original plan.

MIRAGRID PGM G 100/100 is an asphalt interlayer that serves as a barrier, reinforcement, and stress relief. It consists of a non-woven fabric reinforced by high-strength glass fibers. When combined with a sprayed tack coat, it prevents water and oxygen from penetrating the lower layers, reduces stress between the sub-base and wearing course, and provides reinforcement for the new asphalt.
