Repair of potholes in pavements with Molins Products

Pavement deterioration can be a dangerous problem if not properly addressed, as it can lead to potholes, cracks and holes. Therefore, preventive maintenance and repair work is essential to keep pavements in good condition and ensure the safety of road users.

In this article, we explore the elements that influence their deterioration and look at how to repair potholes in the pavement.

Pavement deterioration factors

There are several factors that can contribute to deterioration. One of the main factors is the weather. High temperatures can cause the pavement to lose strength and deteriorate, while low temperatures can cause it to crack and break. Extreme weather conditions, such as frost and heavy rain, can also wear over time.

Another factor that can contribute to deterioration is traffic. The weight of vehicles driving over the pavement can cause cracking, surface wear and subsidence over time. Excess weight, such as heavy trucks, can be especially damaging.

Inadequate maintenance can also contribute to deterioration. If cracks and potholes are not filled in time, they can worsen and cause further damage to the pavement. Lack of sealing can also allow water to seep underneath, causing surface deterioration, thereby weakening the soil and causing the pavement to sink or crack.

How to repair a pothole in the pavement?

One of the first steps in the process of repairing a pavement is to clean the surface of the hole. This is done to remove any debris, dirt and water that may prevent the new mortar from bonding properly. Once the substrate has been prepared, the mixture is mixed and applied to the affected surface. Once the material has been poured, the product is compacted and levelled.

Compaction is vital to ensure that the pavement surface is uniform and that the repair is durable. The following are the materials needed and the steps to be taken to repair the pavement.

Materials you need in the repair of pavements:

The materials required may vary depending on the type of damage and the severity of the repair needed. Some of the common materials used include:

• Repair mortars, screeds and even self-levelling mortars. Depending on the use, thickness and characteristics of the pavement to be repaired, we will use one or more of the recommended mortars. Sometimes it is necessary to apply bonding bridges to improve the adhesion of the material to the substrate.
• Floor sealant: Floor sealant is used to protect the floor surface from humidity, sunlight and other elements that may damage the floor. Depending on its use and situation (indoor or outdoor) we will use acrylic, epoxy and/or polyurethane based products.
• Adhesives for flooring: In the case of giving a ceramic finish to the flooring once it has been repaired, we will use adhesives that are compatible with the chosen ceramic piece. Flexible adhesives are the most commonly used.
• Epoxy mortar: On some occasions, when high mechanical and chemical resistance is required, epoxy mortars, a mixture of aggregate and epoxy resins, can be used to give the pavement these characteristics. These mortars are also used to repair fissures and cracks in the pavement and even to join existing materials.
• Tools: Tools needed for industrial pavement repair may include a chop saw, jackhammer, disc sander, shovel, rake, and hand roller for compacting backfill material.

It is important to select materials to ensure a durable and safe repair.

Step by Step: How to repair a pavement

The following are some general steps that can be taken to repair a pothole in a pavement:

1. Inspect the affected surface: It is important to inspect the pavement to determine its size, depth and extent. Also look for signs of damage to the pavement.
2. Prepare the area: remove any debris or dirt from the pavement and clean the pavement surface thoroughly.
3. Prepare the mixture of the prescribed material, always following the manufacturer’s specifications indicated in the product data sheet.
4. Add the mix, compact it and level the repaired pavement. It is necessary to ensure that the mix is well compacted and levelled with the existing pavement.
5. Depending on the material applied, wait for the necessary time to be able to put the flooring into operation. This may take several hours or even days, depending on the weather and environmental conditions, as well as the product used.
