Why use concrete blocks?

 

Manufactured from cement, sand and aggregates, dense concrete blocks are well known throughout the construction industry for their exceptional durability and strength, which makes them perfect for a number of uses, including building load-bearing walls. A cost-effective solution, concrete blocks also allow for rapid construction on any project, saving you valuable time and money.

Concrete blocks also have a high thermal mass which means they are extremely effective at absorbing and storing heat. When a building is designed and constructed well, concrete blocks help keep it cool during the summer months and warm in the winter. This allows the building to achieve the highest levels of long-term energy efficiency possible and contributes to the building’s overall sustainability and low running costs.

As well as our dense concrete blocks, at Wright Minimix we also offer bulk bags of sand and aggregate and cement waterproof bags. To find out more or to place an order, contact us today on 0117 9582090.

How To Successfully Install A Concrete Shed Base
01st June 2020

Whether it’s for storing tools and gardening equipment or to turn into something a little more fun, a shed is a fantastic addition to any garden. So, if you’re looking to add a shed to your outside space, you’ll need to make sure it has a solid foundation to ensure its longevity and durability which is why we’ve put together this quick guide to installing the perfect concrete shed base.

1) Where will your shed go?

The first thing you’ll need to decide for a successful concrete shed base is where you want the structure to go in your garden. If it’s placed too near a wall it will be difficult to apply your wood treatment and finish and it might restrict your access. Don’t forget if it’s too close to a tree or large plant, the roots may affect the stability of the shed base.

2) Preparing the sub base

Once you’ve decided on your perfect location, it’s time to prepare the ground by:

  • Digging the top layer of soil down to at least a 3 inch depth
  • Constructing a wooden framework that runs the perimeter of the shed base and sit approximately 3 inches above garden level
  • Laying around 3 inches of compacted hardcore (brick rubble is also suitable) and if appropriate, compacted sand.

3) Pouring the concrete

Now you have prepared the ground, all you have to do is sit back and relax as the experts at Wright Minimix prepare the perfect concrete mix for you and deliver it straight to your home. By choosing ready mix concrete, you ensure the concrete you use for your shed base is correct, you order the exact amount you need to reduce waste and ensure you only pay for what you need.

What is reinforced concrete?
19th May 2020

Reinforced concrete is concrete that has steel bars embedded within it. The two materials then act harmoniously to absorb the tensile, compressive and shear forces acting upon it.

Why is concrete reinforcement necessary?

Solid concrete has incredibly high compressive strength. This means that it can cope with large amounts of pressure applied to its surface without breaking. In comparison, concrete’s tensile strength is usually less than 10% of its compressive strength, which makes it vulnerable to forces that could pull it apart, like earthquakes, vibrations and high winds. Steel rebar absorbs tensile stress applied to the concrete and significantly increases its ability to withstand it.

How does concrete reinforcement work? 

When embedded within concrete, steel bars, rods or mesh form a strong bond with the mix as it cures to create what is essentially a single structure. The steel is arranged in such a way to ensure maximum effectiveness in overcoming tensile forces, whilst the concrete makes up for the compressive strength that the steel bar lacks.

Do I need reinforced concrete for my project?

One question that we get asked frequently is if they will require a reinforced concrete slab for their project. Generally, reinforced concrete is recommended for all commercial applications. For DIY projects, it depends on both how large the concrete slab will be and its intended use. If you want to erect a small wooden shed, it shouldn’t be necessary, though you may want to consider steel reinforcement for a large driveway to avoid cracking.


We are proud to be your one stop shop for all things concrete in Bristol, South Wales and the surrounding areas. Whether you are working on a commercial contract or a job in the garden, we can deliver quality concrete mixes straight to you on site. We can even arrange steel reinforcement on your behalf as well.

Why liquid screed trumps dry screed indoors
17th April 2020

At Wright Minimix, our concreting experts maintain that liquid screed is far better than traditional dry screeds when it comes to indoor applications. Read on to find out why.

Speed of installation

Liquid screed will always be faster to install than dry screed. This is because it requires zero spreading or levelling. All you need is a concrete pump and a very limited number of tools to carry out installation. The larger the area you need to cover, the more time (and therefore cost) savings you will make by using liquid screed over a traditional dry screed.

Drying times

Our Wrightflow liquid screed has been specially designed to be quick drying whilst maintaining minimal chance of cracking. This means that your floor could be walked on within 24 hours and is usually capable of full weight bearing within 7 days. This is more rapid than the majority of traditional screeds.

Efficiency with underfloor heating

One of the most compelling reasons to choose liquid screed over a traditional dry screed is its improved thermal efficiency when combined with underfloor heating. This is because liquid screed wraps around the underfloor heating pipes completely and has minimal air pockets that prevents heat distribution throughout the floor. Better thermal efficiency means that you will have to spend less overall on other heating costs to compensate, like turning on radiators.


At Wright Minimix, we have created our own brand of Wrightflow liquid screed to ensure you get the best possible results. To find out more and arrange a quote, contact our team today on 0117 958 2090.

Concrete Curing – How To Do It & What To Avoid
07th April 2020

Why is curing concrete correctly important?

Curing (or drying time) is a very important stage during installation, as this is when concrete develops its strength and durability through hydration. However, curing concrete correctly is a delicate process and means controlling the amount and rate of moisture that is lost through evaporation to ensure optimal results. 

For example, a well-mixed batch of concrete can be made weaker by poor curing, whilst an average slump that is well cured can produce better durability. It is therefore extremely important for the longevity of your concrete that you follow the correct procedure when curing freshly laid concrete.

Do’s & Dont’s of curing concrete

 

Do's

 

Water Curing

The first 7-10 days are essential in the curing process, as this is when the concrete will increase in strength the most. During this period, it is essential that your concrete slab does not dry out, especially if it is in direct sunlight. Misting is a technique frequently used and involves spraying a fine mist of water regularly across the surface of the slab to maintain moisture levels and keep the surface damp at all times.

Cover your slab

If it is not realistic for you to employ the misting technique frequently, then covering your concrete slab with a plastic sheet is the most efficient way to prevent surface water from evaporating. When covering your concrete slab, make sure that the sheet extends beyond the edges of the slab by at least double the depth of the slab. Use bricks, rocks or other heavy items to hold the sheet in place. Remove the sheet daily, wet the concrete, and repeat for at least 7 days.

Don'ts:

Let your concrete get too hot or cold

The ideal temperature to pour concrete is between 10-15°C. If your freshly laid concrete becomes too cold, then the chemical reactions will also slow down. Your concrete therefore won’t gain strength as quickly (if at all if it’s very cold). Concrete insulating blankets should then be used for the first 2-3 days to avoid damage. If you expect the temperature to be higher than 23°C, it is especially important to ensure that that slab does not dry out too fast – keep it hydrated!

Put too much weight on it too soon

Wait at least 24 hours before allowing light foot traffic on your concrete slab and at least 10 days before heavy traffic, like cars, machinery and heavy furniture.
