How do I choose between blocks, flyash bricks and pavers?
Blocks and flyash bricks are for walls: lightweight blocks when weight matters, concrete blocks for general walls, flyash bricks for neat plastered walls. Pavers and tuff tiles are for outdoor floors, and curb stones edge roads and paving. Our materials guide explains each one.
Lightweight blocks
What is the difference between lightweight and standard concrete blocks?
Lightweight blocks use lighter aggregate or an aerated mix, so they weigh less for the same size and insulate better. Standard concrete blocks are denser and heavier, which suits walls that carry more load or need more mass.
Can lightweight blocks be used for load-bearing walls?
Some strength grades can, mainly in low-rise buildings. Your structural engineer should confirm the grade required. Ask us for the strength details of the block you plan to use before you order.
Pavers & tuff tiles
How thick should pavers be for a driveway?
Surfaces that carry cars need thicker pavers than walkways. Tell us the vehicles and traffic you expect and we will suggest from the thicknesses we make, then confirm with your contractor.
What is the difference between pavers and tuff tiles?
Both are precast concrete paving units. In everyday use, tuff tiles usually means heavy-duty concrete tiles made for outdoor floors, while pavers often refers to interlocking or patterned units. Send us your use and we will recommend the right one.
Flyash bricks
How do flyash bricks compare with clay bricks?
Flyash bricks are machine-moulded, so they are more uniform in size and shape than most clay bricks, which makes walls neater. Clay bricks are fired in a kiln, flyash bricks are cured. Strength depends on the mix and curing, so ask us for the details of the batch you are buying.
Are flyash bricks eco-friendly?
They put an industrial by-product, fly ash, to use and avoid digging clay for firing. That is a real material benefit, though the overall footprint also depends on cement content and transport distance.
Curb stones
What is the difference between a curb stone and a kerb stone?
They are the same thing. Curb is the American spelling and kerb is the British one. Both are common in Pakistan.
How many curb stones do I need?
Divide the length of the edge by the length of one stone, then add a small allowance for cuts and breakage. Send us the length and the stone size you want and we will confirm the count.
Concrete blocks
What is the difference between solid and hollow concrete blocks?
Hollow blocks have open cores, so they are lighter, cheaper per block and can take reinforcement or grout in the cores. Solid blocks are heavier and denser, which suits walls that need more mass or carry more load.
Can concrete blocks be used for boundary walls?
Yes. Concrete blocks are widely used for boundary walls. Wall height, wind exposure and soil conditions decide the thickness and any reinforcement, so confirm these with your contractor or engineer.
