FAQs
1. Why Is a Strong Garage Foundation Important?
A garage foundation provides stability and structural support, preventing future issues such as:
✔️ Cracks and movement due to uneven settling
✔️ Water damage from poor drainage
✔️ Structural instability, making garage doors difficult to align
✔️ Shortened lifespan of the garage due to weak foundation work
A properly constructed foundation ensures your garage remains level, durable, and structurally sound for years to come.
2. Types of Foundations for a Garden Garage
Depending on soil conditions, budget, and the structure’s weight, different foundation types may be suitable:
🔹 Concrete Slab Foundation – A cost-effective and highly durable option.
🔹 Strip Foundations – Ideal for garages with brick or block walls.
🔹 Raft Foundations – Best for softer ground, distributing weight evenly.
🔹 Piled Foundations – Necessary for weak soil conditions, using deep supports.
Our recent garage foundation project utilized a reinforced concrete slab, ensuring long-term stability and resistance to environmental factors.
3. Planning and Site Preparation
Before beginning any garage foundation project, proper planning is essential:
✔️ Site survey and soil testing – Ensuring suitable foundation type.
✔️ Clearing and leveling – Removing debris and vegetation for a flat base.
✔️ Marking out dimensions – Measuring the exact area for excavation.
✔️ Securing planning permissions – If required by local authorities.
Our recent garage foundation build followed strict planning and ground preparation procedures, ensuring a smooth and trouble-free installation.
4. Excavation and Groundwork
The excavation process is crucial for creating a stable base. This involves:
🔹 Digging to the required depth – Providing adequate support.
🔹 Installing shuttering (formwork) – Holding the concrete in place.
🔹 Laying a compacted hardcore base – Improving stability and drainage.
🔹 Adding a damp-proof membrane – Preventing moisture penetration.
Our team at TWL Groundworks ensured precision at every stage, reinforcing the foundation for long-term durability.
5. Concrete Pouring and Finishing
Once the groundwork is complete, the concrete foundation is poured and finished:
✔️ Mixing and pouring – Using high-quality concrete for strength.
✔️ Reinforcing where needed – Adding steel for extra support.
✔️ Leveling and smoothing – Ensuring an even surface.
✔️ Allowing curing time – Ensuring proper hardening before further work.
For our recent garage foundation project, we achieved a perfectly level surface, ready for the next phase of construction.

7. Drainage Considerations
Effective drainage is crucial for preventing water pooling around the foundation. Our approach includes:
🔹 Installing perimeter drainage to divert rainwater.
🔹 Slightly sloping the foundation for natural runoff.
🔹 Using gravel and drainage channels to improve water flow.
By integrating proper drainage solutions, we ensure long-term protection against water damage.
8. Common Foundation Mistakes to Avoid
To achieve a flawless foundation, we avoid these common mistakes:
❌ Skipping soil testing – Leads to instability.
❌ Poorly compacting the base – Causes sinking and cracks.
❌ Pouring concrete in extreme weather – Weakens the foundation.
❌ Ignoring drainage solutions – Increases the risk of water damage.
With TWL Groundworks, you can trust that every foundation project is built to last.
