How Do You Fix Standing Water on Asphalt?
Standing water on your asphalt pavement is more than just an eyesore; it’s a serious threat to the integrity and longevity of your investment. Whether it’s a puddle in your driveway or a pool in your parking lot, standing water on asphalt can lead to costly damage and safety hazards. This guide will explore the causes and consequences of standing water, and outline effective solutions to eliminate it and protect your pavement.
Why Standing Water on Asphalt is a Problem
Asphalt, while durable, is a porous material. When water is allowed to pond on its surface, it can seep into the pavement structure, causing a range of problems:
- Weakening the Base: Water that penetrates the asphalt can weaken the underlying base and subgrade layers, leading to instability and potential pavement failure.
- Cracking and Potholes: As water seeps into cracks and freezes, it expands, causing the cracks to widen and eventually form potholes.
- Raveling: Standing water can contribute to raveling, where the asphalt’s aggregate (stones) loosens and comes apart, creating a rough and uneven surface.
- Reduced Lifespan: Water damage accelerates the deterioration of asphalt, shortening its lifespan and leading to costly repairs or premature replacement.
- Safety Hazards: Standing water can create slippery conditions, increasing the risk of accidents for both vehicles and pedestrians.
Causes of Standing Water on Asphalt
Several factors can contribute to standing water on asphalt:
- Improper Drainage: Inadequate sloping or clogged drains can prevent water from flowing away from the pavement surface.
- Cracks and Potholes: These imperfections allow water to penetrate the asphalt and reach the underlying layers.
- Poor Installation: Improper compaction or inadequate base preparation during installation can create low spots where water accumulates.
- Ground Movement: Over time, the ground beneath the asphalt can shift and settle, creating depressions that collect water.
- Excessive Rainfall: While a well-designed pavement can handle normal rainfall, heavy or prolonged rain can overwhelm the drainage system and lead to ponding.
How to Fix Standing Water on Asphalt
Addressing standing water on asphalt requires a multi-faceted approach that addresses both the cause and the consequences of the problem.
1. Improve Drainage:
- Ensure Proper Sloping: The asphalt surface should be sloped at least 1% to 2% to allow water to flow towards drains or designated drainage areas. Re-grading may be necessary to correct improper sloping.
- Install or Repair Drains: Install or repair catch basins, French drains, or other drainage systems to effectively channel water away from the pavement.
- Clean Drains Regularly: Remove debris and leaves from drains and catch basins to prevent clogging and ensure proper water flow.
2. Repair Cracks and Potholes:
- Prevent Further Damage: Repairing cracks and potholes prevents water from seeping into the pavement structure and causing further deterioration.
- Professional Repair: Engage a qualified asphalt contractor to ensure proper repair techniques and materials are used.
3. Apply Sealcoat:
- Create a Protective Barrier: Sealcoating creates a protective layer that helps prevent water from penetrating the asphalt surface.
- Regular Application: Reapply sealcoat every 1-3 years to maintain its effectiveness.
4. Address Underlying Issues:
- Ground Movement: If ground movement is contributing to ponding, address the underlying soil conditions to stabilize the base and prevent further settlement.
- Poor Installation: If the problem stems from poor installation, consider removing and replacing the affected section of pavement to ensure proper drainage and compaction.
5. Preventative Measures:
- Regular Maintenance: Regular sweeping, cleaning, and inspections can help identify and address potential drainage problems before they become major issues.
- Proper Compaction: During installation, ensure proper compaction of the asphalt and base layers to prevent low spots and promote proper drainage.
Repair cracks & potholes
While water damage can’t be reversed, repairing cracks and potholes can prevent further amounts of water from seeping into your asphalt. Make sure to contact a trusted paving company to repair your asphalt.
Reapply Sealcoat
To help block out water, we recommend applying a seal coat every 1-3 years. This will seal even the smallest of cracks, and prevent water from infiltrating your asphalt.
The best way to prevent pooling water from forming is to hire a reliable asphalt paving company. Our experienced team will install your asphalt base, do any patching, and ensure you have a proper drainage system in place. It is also very important that after your asphalt is applied, you wait the allotted amount of time before using your driveway or parking lot. This is because, if driven on too soon, you can cause cracking.
