Maintain your outdoor basketball hoop apparatus with this H2Old Base Gel. It effectively replaces sand or water as ballast weight for portable basketball base supports. This base gel polymer absorbs up to 400 times its weight in water, creating a firm, stable gel that will last up to seven years. It also resists leaks if small holes or cracks develop in base. This gel is durable enough for use in any climate, even during harsh winter conditions.
