Add insulation

Before suing any insulation on your crawl space, it is good to check the R-value of the material.

Use insulation with a higher R-value since it has a higher thermal resistance.

The size of the cavities in your crawl spaces will help you determine the insulation R-value to go for.

For huge holes, it will require more efficient insulation.

Be cautious with the insulation.

Make sure you install properly; otherwise, it will lose its effectiveness.

Ensure it fits inside the joists accurately.

However, do not over compress it since it will reduce its insulating abilities.

The pipes will direct water to the lowest pint of the crawl space.

The pump will then get the collected water outside your home to a gutter system.

You can install a backflow device to prevent the water from flowing towards the direction of your home when water levels rise.
