We investigated purely gravitational domain wall solutions to Horavanonrelativistic theory of gravity with detailed balance in 3 + 1 dimensions. Wefind that for arbitrary values of the running parameter {lambda} > 1/3 twobranches of membrane solutions exist. For positive values of the cosmo-logicalconstant, the solution represents a space that is bounded in the transversedirection, with singularities sitting at each of the boundaries. For negativevalues of the cosmological constant, the solution contains a single membranesitting at the center of a space, which extends infinitely in the transversedirection approaching a Lifshitz metric. In that case there is one additionaldegenerate branch, for which the lapse function is undetermined.
