 LAY A CONCRETE BASE WITH OUR POURING CONCRETE 

With the help of our step-by-step guide, along with our ready-mix pouring concrete system that enables you to only ever be charged for exactly what your  project requires on the day of pouring, you will be well on your way to getting summer outdoor living ready in the most affordable way possible!

STEP 1 - Choose project location

HOW TO SHED BASE.JPG

It is important that, depending on your project, you ensure it is in the correct location to get the most out of your imminent outdoor living space.

For example, if your concrete base is for a summerhouse, you may need to think about whereabouts in your garden you get the most daylight hours and position it to suit.  

 

If your concrete base is for a shed, you may need to ensure that you have left enough room around the concrete base to enable sufficient access for its planned use. You may also need to consider if you require services such as water and electricity before you choose the location of your project.

 

For all projects that require a concrete base, try to leave a one-meter gap between any surrounding walls or fencing. This will allow for access of maintenance of any weeds and will enable you to, if applicable, treat or paint any timbers.

Please note- always check your manufacturers fitting instructions prior to creating a base for your projects!

STEP 2 - Levelling the ground for your base 

This is a crucial stage in the project.

 

Failure to ensure a level ground could potentially compromise the standing of any laid ready-mix concrete and, over time, could interfere with the longevity of the project.

 

Using string, pegs and a tape measure, mark out the required area of the concrete base. Adding an extra 30-40mm to each side is also suggested.

 

You need to ensure each corner is 90-degrees. This can be achieved by using a builders square set.

 

Remove all vegetation and lawn from with inside the marked-out area and dig down to a minimum depth of 150mm. This is to allow for 75mm of hardcore and 75mm of pouring concrete.

 

Add the hardcore and ensure it is level. This can be achieved by compacting it with a vibrating plate.

STEP 3 - Creating a timber frame

Before any pouring concrete can be laid, a timber frame will need to be constructed. This is to allow the ready-mix concrete to set without it running out of your base boarder. 

You will need to cut 4 timber frame pieces to the exact size of strings created in step-2.

 

Reminder! - The inside measurements of the timber frame need to match the dimensions of your desired concrete base.

 

Diagonally measure corner to corner. These measurements need to be correct to ensure you have a perfectly square space.

 

You will then need to use a spirit level to check the timber frame sits level on top of the hardcore- make any adjustments If needed.

 

In order to ensure your concrete is level whilst it is being poured, you need to add several wooden pegs within the area of the base.

STEP 4 - Ordering your pouring concrete

The next step is to order your ready-mix pouring concrete with Pick N Mix Concrete 

Use our handy concrete calculator to determine how many cubic meters of concrete you need to order.

 

Alternativley, you can simply call us on 01782 980442 and provide us with the length x width x depth of your timber frame and we can calculate how many cubic meters are required for your project.

Unsure on your measurements? Not to worry! At Pick N Mix, if you provide the incorrect measurements and once we get to your property you require more or less concrete, we can either pour less than you ordered or mix more onsite to meet your requirements!

With Pick N Mix Concrete, you only ever pay for exactly what you need once we get to your site! 

STEP 5 - Pouring your concrete into the base frame

Pour a layer of concrete into the frame, making sure that concrete reaches all four corners and all edges. The concrete will need to be spread evenly and compacted with a rammer.

Tap each side of your frame with a hammer to knock out air bubbles enabling you to achieve a nice solid edge to the slab.

 

Continue pouring and spreading layers of concrete until it slightly overfills the frame.

Next, use a length of timber as a ‘tamping beam’ to compete a ‘sawing’ motion across the slab, working from one end to the other. This will level off the concrete ensuring that it is flush with the top of your frame.

Finally, use a spirit level to ensure you have a flat, even surface.

Leave your new concrete base to set for at least three days before removing the frame. If it rains, cover it with plastic sheeting.

 

It is also equally as important to not let it dry out too quickly, therefore, in warm weather, prevent cracking by spraying it with water and covering with damp cloth.
