Ideally, when you build your shed, summer house, outhouse or man cave in Surrey or London, it should always sit on a concrete base.

The base is an essential part of building a shed (whether they may be wooden or metal garden sheds), the base has to be properly made to give your shed a solid foundation. If your building a shed base or any other building for that matter such as summer house, log cabin, man cave or simple garden storage in London or Surrey  Concrete Design Team make it easy low cost and stress free.

Concrete Bases – The Process

1. Marking Out Your Concrete Base

Decide where to position your garden concrete base. We will construct it 2 inches larger than the area of the building on each side, or more if requested. You might want an extra square level platform at the door entrance.

2. The Form Work

Concrete Design Team Start by setting out a levelled formwork using a laser level and levels. This involves measuring, cutting and fitting timber to the shape of the base in order to contain the concrete. We check diagonal measurements to ensure the formwork is square and level, as this will determine whether your shed base is 100% sturdy and level.

3. Ground Preparation

The biggest threat to a concrete slab in the garden comes not from what gets built or parked on top, but what might move below. If the soil or base beneath the slab shift or settle, the result can be a cracked slab.

We removing any stones and other debris from the surface, before digging to get rid of the top layer of soil. We keep the surface even throughout, fully compacting any filled in areas to ensure that slabs don’t bend and crack once laid due to an uneven base. Next, we put down a layer of MOT type 1 or crushed concrete at approximately 4 inches in thickness and compact. Not only does this help to level out the concrete that’s laid on top of it, it also provides an insulating layer and allows moisture to escape. We then create a vapour barrier with a damp proof membrane, designed to stop water rising through porous concrete and allowing the concrete to move in different weather conditions.

4. The Concrete

The concrete slab should be approximately 4 in. thick depending on what the concrete base is going to be used for.

Concrete Design Team will use a concrete mix to suite your project depending on what the concrete base is going to be used for, we will add Fibre reinforcement it’s inexpensive product that we insist on in the concrete. The fibers are mixed in with the concrete to produce a stronger slab.

5. Finishing and Curing

Once the concrete has been poured, it needs to be levelled and smoothed in large areas Expansion joints are cut into the concrete to provide additional crack resistance. Then, the new slab needs to be left alone. Concrete doesn’t dry out; it undergoes a chemical curing process that creates a dry, solid mass.

Concrete Design Team can offer a wide variety of finishes for your garden concrete base in London or Surrey,

Tamped Concrete Finish – this is a cost effective concrete laying solution that produces a rougher surface.

Bull Floated Finish – produces a smother slightly textured surface which often contains float marks.

Brushed Finish – producing high slip resistance and allowing the water to drain to the falls created. Brushed finishes are suitable for areas trafficked either by vehicular or foot traffic and are also suitable for many types of mechanical handling plant.

Power Floated Finish – this is a hard wearing finished surface Power float machines are fitted with circular pans to help smooth the concrete before metal blades are rotated over the surface to achieve a hardened surface.

Before the concrete can be power floated it has to be left to harden, so concrete installed in the morning cannot usually be power floated until late afternoon dependent on the outside conditions. Power-floating produces a flat smooth dense finish. (Power floated floors are hard wearing and require no further finishes, however, resins, polishing and screeds can all be applied to the surface.)

Epoxy Resin Finish– produce a low maintenance and durable floor that help reduce dust problems and provide a beautiful and comfortable work surface.  Available in our wide range of colours and textures, they are attractive and are used in both domestic and commercial floors take a look at our resin floor page.
