You already own one of doppler's stylish and functional umbrellas, but are afraid that it will lose its grip and tip over in the wind or rain? Then we have just the thing for you. Our concrete bases weigh between 20 and 42 kilograms and reliably ensure that your umbrella does not lose its grip. Depending on their weight, the concrete bases are suitable for both small and large sunshades and come in a modern plastic look or in a PVC coating with an elegant granite design.
