FAQ about exterior concrete
How much does an exterior concrete driveway cost?

How long does a concrete staircase or sidewalk last?
Properly poured and maintained concrete can last between 25 and 40 years. Our installations meet industry standards and are designed to withstand Quebec winters.
How to prevent cracks in exterior concrete?
Cracks often appear when ground preparation is neglected. At Groupe A1, we ensure that excavation and formwork comply with standards, and use expansion joints to limit the risks.
Does exterior concrete require maintenance?
Concrete is undemanding, but it is advisable to clean it with water, avoid abrasive salt in winter and apply a protective sealant every 3 to 5 years to prolong its durability.
Concrete or paving stone: which to choose?
Concrete is often preferred for its sturdiness and cost-effectiveness, while interlocking paving stones offer greater scope for personalization. Groupe A1 offers both solutions and can advise you according to your needs and budget.

Yes, we can correct cracks, settling, damaged joints or damaged surfaces to extend the life of your existing fixtures and fittings.
