Lytag lightweight aggregate is used extensively in a variety of precast products, such as lintels, kerbs, panels, stairs and bespoke units. Its weight saving properties can lead to significant advantages in production techniques and logistics. Larger panel sizes may reduce the number of joints required thus speeding up construction and reducing the cost of jointing and moulding.
  
Wall and floor panels are more resistant to accidental loading, and absorb more energy in the elastic range than natural aggregate concrete. Additionally, the thermal properties are improved when compared with natural aggregate concrete. These benefits allow for significant overall cost savings to be made, and makes Lytag the natural alternative.

*  Using Lytag coarse and fine aggregate
 

25% lighter
Using Lytag aggregate the weight of concrete units can be reduced by around 25% over natural aggregate concrete. Including Lytag fines can reduce the weight even further.

Logistical advantages
Using Lytag aggregate reduces the weight of precast units; therefore more units can be transported on one vehicle. This reduces both vehicle  movements and transportation costs, also creating a positive impact on the environment.

Easier fixings
Using lytag aggregate improves accuracy of fixings and reduces tool wear due to less resistance from the coarse particles during drilling.

Cranage
Using Lytag aggregate produces lighter precast units, therefore larger panels can be cast or crane capacities can be reduced.

Enhanced design capabilities
Using Lytag aggregate gives the designer greater flexibility in design concepts by allowing benefits such as larger floor or roof spans, lighter precast units with insulation properties, savings on foundation size and costs.

Manual handling
Using Lytag aggregate in precast units such as flags and kerbs, which traditionally are laid by hand, reduces weight, thereby reducing the potential for strains or accidents due to manual handling.

Larger units
Using Lytag aggregate reduces the weight of precast units, therefore allowing the designer to take advantage of using larger units. This can reduce the cost of casting and jointing, speeding up construction.
