Like most parts of a building, concrete steps are prone to water damage, which can lead to them becoming cracked and leading to more serious structural issues causing you or the property problems later down the line, which would later have to be repaired, prevention is better than cure after all.
Concrete step waterproofing involves applying sealants or waterproof membranes and prevents water damage, extending the lifespan of the steps.
The Importance Of Concrete Step Waterproofing
Preventing Water Damage
As previously mentioned, water damage can weaken concrete over time and concrete steps are no different. Water seeps into the cracks and pores of concrete causing it to break down over time, this occurs in a variety of different ways:
- Water freezes and expands in cracks.
- Constant moisture can lead to mold growth.
- Water can wash away the concrete’s minerals.
Waterproofing helps to block water from entering the concrete keeping it dry, by doing so you’ll prevent water damage ensuring your concrete steps remain intact and safe.
Extending The Lifespan Of Concrete Steps
Through waterproofing you’ll help to extend the lifespan of the concrete steps keeping them in a better condition, for longer. This comes with a host of benefits, including:
- Reducing the need for repairs.
- Saving money on maintenance.
- Enhances the durability of the steps and the structural integrity of the property.
In addition to these, by waterproofing concrete you also add a protective layer to it. This layer helps keep out dirt and oil which will also damage concrete over time.
Common Waterproofing Methods
Now we’ve covered the importance of waterproofing your concrete steps, it’s time for the most common methods of waterproofing them so you can start the process as soon as possible.
Sealants And Water Repellents
Sealants and water repellents are a popular form of waterproofing. These types of methods create a barrier or additional layer to the surface. This barrier prevents water from permeating the concrete.
Sealants are often made of silicone or acrylic and are applied directly to the surface of the concrete, filling in cracks and covering pores in order to keep the water out.
Water repellents, on the other hand, work differently. They don’t fill cracks but create a water-resistant surface. This makes water bead up and roll off. Some common water repellents include:
- Silane
- Siloxane
- Fluoropolymer
These types of substances can be sprayed or brushed on making application easy and quick, however these tend to wear off faster and reapplication might be needed every few years.
Both sealants and water repellents protect concrete from damage, are cost-effective and efficient, making them a DIY favourite for many homeowners.
Membrane Waterproofing Systems
Membrane waterproofing systems are another solution, but may not be the best choice for those looking for a DIY option. These systems involve applying a waterproof layer over the concrete which acts as a shield against water.
There are two main types of membrane systems:
- Liquid Membranes
- Sheet Membranes
Liquid membranes, as the name suggests, are applied as a liquid. They form a rubber-like coating when dry creating a seamless and flexible finish. The main benefit of liquid membranes is that they can cover all areas over the steps, including corners and joints as well as being easier to apply on uneven surfaces.
Sheet membranes, on the other hand, come in rolls. Similar to liquid membranes they cover the concrete, but differ as these are more permanently attached. These sheets are usually made of bitumen or rubber and provide a thick, durable layer of protection with a more consistent thickness.
Overall membrane waterproofing systems are highly effective providing long-lasting protection which is ideal for areas with heavy water exposure.
Bonus: Using Asphalt For Waterproofing
Another choice for waterproofing steps is Asphalt. This technique has been used for centuries and is often referred to as the ‘king of waterproofing’ due to its durability, versatile properties and ability to withstand harsh environmental conditions, as well as its cost-effectiveness.
The main benefit of asphalt is its ability to expand and contract with temperature changes without cracking ensuring long-term performance and minimal maintenance. Not only that but its thermal flexibility is particularly advantageous in regions with extreme weather variations.
This type of waterproofing will however require professional implementation.
In Summary
Waterproofing your concrete steps is something that is often overlooked by many homeowners and catches them out. Thinking about it earlier rather than when you have to will help you prolong their lifespan, prevent structural damage to the wider property and save you money in the long run.
Whilst it can be done as a DIY option, sometimes is best left to professionals like Bell Asphalt Co to ensure it’s done properly and to a standard that’s hard to replicate. Experts that do this day-in day-out can also ensure the right option is used for your particular circumstances in addition to using the right materials.
