Lytag® LWA is a versatile, lightweight aggregate produced from pulverised fuel ash (PFA), a by-product of coal-burning power stations. A truly environmentally friendly material, Lytag® LWA provides an excellent alternative to natural, quarried aggregate, being strong, light and consistent. Lytag® LWA can be used for many varied applications, including: |
|||
|
> Land drainage
Lytag® LWA is an ideal medium for land drainage applications. Its rounded shape and regular grading give excellent hydraulic conductivity. |
|
> Precast lightweight concrete
The weight-saving properties of Lytag® LWA can lead to significant advantages in production techniques and logistics when used in the manufacture of precast concrete. |
|
> Lightweight floor and roof screed
Lytag® LWA floor and roof screeds offer a wide range of benefits including cost and weight savings in addition to considerably enhanced thermal and sound insulation. |
|
> Geofill®
Using Geo fill® civil engineering bulk fill either bonded (with cement) or unbonded (loose) for maximum flexibility, the free draining properties allow significant reductions in hydrostatic pressure |
|
> Structural lightweight concrete
Structural concrete can be produced with an effective reduction in dead weight over that of normal weight concrete allowing architects and structural engineers a wider range of opportunities in design. |
|
> SUDS
By combining excellent drainage and moisture retention properties, LytagŪ LWA is an ideal medium for many areas of a SUDS system. |
|
> Green Roofs
Using Hortag® horticultural medium for drainage and part of the soil/growing medium helps reduce weight and improve drainage and moisture retention properties. |
|
> Other applications
Due to its particular and varied attributes, Lytag® LWA is extremely versatile and can be used for a wide range of other applications. |
