Common Causes of Concrete Drainage Issues Blocked or Insufficient Drains: A lack of proper drainage systems or clogged drains can cause water to collect, leading to runoff issues. Cracks or Gaps in the Concrete: Over time, even small cracks can allow water to seep in, leading to larger drainage problems.
You've got a few options: as others have said: 1- drill weep holes & seal wood so it doesn't rot. 2- pull some pavers & dig to install a drain. 3- plane down the wood/notch the corner so it drains over the edge (my personal fav) 4- pull pavers & re-level patio so it's above the wood & pitched proper again.
You can install a swale or French drain, which channels the water away from the site to an area where it won't cause problems. You can divert water to another spot on your property but not to the neighbor's yard, so if you can't shift the water to a good location, you'll have to run a French drain to a dry well.
Where the water tends to collect, cut out a sloping channel in the concrete to direct the water away, filling it with decorative stone or gravel. Instead of gravel, you can also have a trench or channel drain made of metal installed.
Repitch With Bare Concrete
In this latter application, you will first need to scarify the concrete to the proper concrete surface profile (CSP) according to the application instructions of the waterproofing system chosen to repitch the deck. After scarifying, clean the area and blow with a blower.

When warm air comes into contact with a colder temperature concrete slab, the condensation will build up on the surface and can commonly be defined as concrete sweating. The combination of temperature swings and humidity build up cause the concrete to sweat.
If the water is seeping through the concrete walls themselves, it may be necessary to waterproof the exterior of the walls. This may involve applying a waterproof coating or membrane to the walls or installing a drainage system to direct water away from the building.
Debris, such as leaves, soil, or twigs, can accumulate in drainage channels, eavestroughs, and gutters, blocking the water flow. When these channels are clogged, water is prevented from draining away efficiently, leading to pooling issues on your patio.
Drilling holes in concrete to create water drains is a technique that seeks to address water-related concerns directly. By providing an outlet for water to escape, this method aims to reduce the chances of freeze-thaw damage and hydrostatic pressure buildup.
Boiling Water
Boiling water is another simple and effective drain-cleaning hack. Boil at least a quart of water and slowly pour it down the drain in smooth spurts. You need to give the water time to work its way through clogs and destroy blockages, so don't pour it all at once.
Excess water can damage weak or unprotected concrete. Water seeping into soils beneath or pooling on top of your concrete slab can contribute to cracked concrete, sunken concrete, and even foundation settlement.
Where the water tends to collect, cut out a sloping channel in the concrete to direct the water away, filling it with decorative stone or gravel. Instead of gravel, you can also have a trench or channel drain made of metal installed.
Water erosion is one of the most common reasons for a patio to sink or dip over time. Below all of the foundation gravel and sand is all-natural soil. This soil can be affected by water erosion causing a dip in your patio.

If the existing concrete patio lacks a drainage system, it is a practical move to install one. In areas where the rainwater collects, cut a sloping channel. A well-cut channel directs the water away from the patio. Fill the channel with decorative stones or gravel so it meets aesthetic ideals.
One option is to reslope the soil surrounding the area, allowing for proper drainage. Another option is to install a French drain, which will redirect the excess water away from your concrete surface.
If a peril that's covered by your homeowners insurance policy results in a plumbing leak under your slab creating a slab leak, your homeowners insurance policy might help pay to tear out and replace the slab and repair the water damage to your home.
Even moisture can make its way up through the concrete, causing dampness and mold. While most homes experience hydrostatic pressure, it is usually alleviated with proper drainage and water prevention.
Typically, a porch sinks when the ground beneath it is compromised. This can be due to environmental factors or construction errors. Common causes include: Soil Compression: Uneven soil settling, where some parts are compressed while others stay unchanged, leads to many porches sinking.
One of the simplest solutions is to add more cement, aggregate and sand to your mix. This can help absorb some of the excess water and bring your mix back to the ideal consistency.
It is important to protect your floors from excessive moisture by using appropriate moisture barriers such as polyethylene sheeting, epoxy sealer, and concrete moisture sealers. Proper ventilation and dehumidification can help keep humidity levels low and prevent dampness from forming in concrete slabs.
